SHUTTER OPERATING AND SECURING.MECHANISM.. i

Application filed April 14, 1522. Seria1 'No.552,6 53.

To all whom it may concern Be it known that I, EVERETTE RAnn, a citizen of the United States, residing at Lewisville, in the county of F orsyth and State of North Carolina, have invented new and usefullmprovements in Shutter Operating and Securing Mechanism, of which the following is a specification.

The object of my present invention isthe provision of simple, easily-operated and efficient means through the medium of which shutters may be opened and closed and secured in closed and open positions from a point within a room and without raising a 5 window sash.

To the attainment of the foregoing, the

invention consists in the improvement as hereinafter described and definitely claimed. In the accompanying drawings, forming 0- part of this specification Figure l'is a fragmentary elevation-with the door of the cabinet in open position.

Figure 2 is an elevation of portions of shutters and certain elements of my improvement.

Figure 3 is an enlargedhorizontal section on the line 33'of Figure 1, showing the parts of my improvement in the positions they occupy when the shutters are closed as v indicated by dotted lines.

Figure 4 is a similar view with the shutters secured in open position.

Figure 5 is an enlarged detail vertical section taken in the'plane indicated by the line 5-5 of Figure 2.

Figure 6 is an enlarged detail horizontal section taken on the line' 6-6 of Figure 2.

Figure"? is a detail vertical section show-- ing the locking of the shuttersin closed posi- Figures 8 and 9 are detail vertical sec tions hereinafter specifically referred to; Figure 8' being taken on'thel'line 8-8. of Figure 4, looking inwardly, and Figure 9 being taken-0n the line'9 -9 of Figure 4,

looking outwardly.

Figure '10 is an enlarged sectional view of one of the operatingrods.

- Figure 11 is an enlarged perspective of oneof the arms on said shaft.

' Figure 12 is an enlarged plan view of one of the shutter pinions. I

Similar numerals, of reference designate corresponding parts in all of the views of .55 the drawings.

1 The window casing, the sashes and the shutters are, in general, oftheordinary well 1 known 5 construction, the shutters being ,des ignated by the numerals 4 and 5. It will be noted, however, Figure 7, that the outer shutter 5 which is adapted when closedto overlap the shuttern4, is provided in its lower end with a socket.6;' also, that the pintles 7 of the lowershinges of the shutters 4 and 5 are utilized as journals for pinions 8 Figures (2,' 5, 6 and 12) on which are bi furcated portions 9 that straddlethe hinge members 10 fixed to the shutters 4 and 5 so that swinging of the said shutters 4 and 5 1 will cause-turning of the pintles 8.

Intermeshed witlrthe pinions 8 are horiwhich arelpr'ovided attheirlower endswith gears 18,,Figures (3, 14:and5). Thesaid, i d v gears 13 are meshed with sector-gears 14 forming the outer armsof horizontal levers, fulcrumed at 15, and provided" with inner arms16.

Appropriately secured in the base portion of the window casing at the-inner side thereof is a cabinet body 17, Figures (1, 3fand 4) Zontal sector-gears 11 on upright shafts 1 2 having a hinged'door 18 on'which is a fastener 19 to detachably Secure i in closed position, 3

Guided in the innerwaIlQO of the casing.

body 17 are shutter-operating rods 21, pivotally connected at 22 to the'levers lfikand having handles or finger pieces 23.

scopic sections 24. and 2 5; adjustably fixed to each other by a set screw 26. From this.

h of the said rods is preferably formed of tele it follows that, saidrodsmay bez-i ncreased' or diminished inlength to suit the thickness of the window casing to which my improvementis applied. p

It will 'beapparent from-the foregoing that when the shutters '4 and 5 are unlocked,

outwardthrust of the' rods 21, positioned as shown in (Figure 3), will bring about open- 1 ing of the shutters 4 and '5, while inward pull on the rods 21,;positioned as in, (Figure 4), will cause closing. of .theshutters 4 and 5,

the shutter 5'being opened first'andclosed .last. I

Carried by. the rods and preferably fixed to the sections 24 thereof are arms 27,

, (Figures 3, 4, 9 and 11). r

I At 28 is a vertical sleeve in .the lbase tion of thewindow casing, -and;at 29 is a vertically-movablebolt, guided inithe sleeve 28' and adapted to enter the socket 6 when the outer shutter 5 is in closed position, (Figure 7.) The said bolt 29 is provided with arms 30v and 31, and a retractile spring 32 is connected to the arm 31 and tends to retract the bolt and release the shutter 5. A horizontal rock. shaft 33 1s journaled' in the wall 20 of the cabinet body 17 and in a fixed bearing 34 arranged inthe outer portion of the window casing 1, (Figures 3; and 7.) Said shaft 33 is provided within the cabinet body 17 with a handle 35, (Figures 1, 3 and 4.) At its outer end the shaft 33 has fixed thereto an armor disk 36 on which is a stud 37 that rests under and in engagement with the arm 30 on the shutter locking bolt 29-. Thus when the handle is in the position shown in (Figures l and 3), the bolt 29 will be secured against downward movement and the shutter 5 will be locked in closed position. When, however, the handle 35 is turned through a quarter of a revolution as indicated by dotted lines in (Figure 1), it will be noted that the spring 32 will be enabled to retract the bolt 29' and release the shutter 5.

As before indicated outward thrust of the rods 21 to the positions shown in (Figure 4) is necessary for the opening of the shut ters 4 and 5.

For the purpose of locking and securing the shutters in open position I provide the rock shaft 40 igures 3, 4, 8 and 9) with a handle 41 in the cabinet body 17 and with an arm 42 against the outer side of the wall 20 and adapted to be engaged against stops 43 and 44 on said wall 20. The outer end. of the shaft 40 is journaled in an appropriately fixed bearing 45, (Figures 3 and 4), and' near said bearing the shaft 40 has fixed thereto a plate 46, (Figures 3, 4 and 9.) Manifestly when the arms 27 are located as in (Figure 4), the shutters 4 and 5 being open, and the shaft 40 is turned about its axis to arrange the plate 46 as shown in Figure 10 relatively to the arms 27, the plate will prevent inward movement of the arms 27 and hence the shutters 4 and 5 cannot close. When, howevergthe shaft 40 is rocked to carry the arm 42 from the stop 43 to the stop 44, (Figure 8), the plate 46 will be positioned to clear the arms 27, and

v the shutters 4 and 5 can then be closed by inward pull on the rods 21,

It will bereadily understood from the foregoing that all of the manipulations described can be made from within a room without the necessity of raising the lower sash of the window.

I have entered into a detailed description ofthe construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my invention as defined in my appended claims.
